.IMPROVEMENT IN PORTABLE lBO0KHOLDERS.

The Schedule referred to in these Letters 'Patent and making part of the lame.

I. CALVINv W. SHERWooD, of the city of Chicago, in-thecounty of Cook and State of Illinois, have invented certain new and useful Improvements in Book- Garn'ersfot' which, the following is a full description, reference being Ihad to the accompanying drawing making a part of this specification, in which- Figure l is a side view.

Figure 2, a top view.

Figure 3, a persepective.

My invention consists in providing a hook-carrier with a wheel-handle, so constructed, applied, and ar'- ranged that it is adapted to be used for the further purpose of tightening the cord `of the carrier.

In the drawing- A A' represent the upper and lower bars of the carrier, betweenwhieh the books are to be placed, about which there is nothing peculiar.

B B are standards, which are secured to the upper har A, one on each side. That the standards may be strong and securely fastened to the bar A, I make them, as shown in the drawing, with two legs, and on the inside of eachleg provide a flange, e, so that the standards can be securedv to A at the points f and e.

Near the top of each standard isv a hole, which servesas a hearing for' the axle al.

C is the wheel-handle, having an axle, d, and a suf-l iicient-nur'nber of bars, 1), connectiuglthe axle l 'with the rim C.Y Thisrim is provided on the. periphery with'any suitable number of projections c parallel with the axle.

b is a pawl loosely attached to the bar A at g, so that it can be turned away from the wheel C, as shown by dotted lines in iig. 2.

c is a cord passing through the bars A A', in the usual manner. This cord passes through the wheel C from one side to the other, as seen in figs. l and 2, so that when the wheel C is turned around the cord will he caught by thebar D, aud,be wound upon the axle d upon each side of the bars D. t

When, by turning the wheel 40, the requisite strain .upon the cord c has been produced, the wheel will be held in place and be prevented from turning back by the pawl or stop b coming in contact with some one of the projections a., and the saine can be easily released by turning the pawl b away from the rotating handle U. v

"lhewh`eel C serves the purpose ofa handle for the carrier in whatever position ythe same may be.

Insteadof projections the wheel may be provided with notches to receive the end of the pawl.

If the cord c shonldbreak it Ycan be readily read'- justed, it only being necessary to pass the same through the wheel-handle as above described and tie the two ends together.

'lhe wheel C and standards B may be cast from any CALVIN W. SH ERVVOOD.
